An endurance swimmer has finished the first swim under the Antarctic ice to demonstrate the “very rapid changes” caused by climate change.
Lewis Pugh, from Plymouth, braved the freezing waters of the supra-glacial lake in nothing more than his swimming trunks, cap and goggles.
He said melt waters could be seen everywhere during his 10-minute swim in water that was just above 0°C (32°F).
It follows reports of ocean temperatures reaching an all-time high.
